The patch
regulator: lp8788-ldo: Let core handle GPIO descriptor
has been applied to the regulator tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
From 2bb8ede0b14187c19b5eedc62cf0b18b3bf00d3b Mon Sep 17 00:00:00 2001 From: Linus Walleij <linus.walleij@linaro.org> Date: Thu, 6 Dec 2018 13:43:40 +0100 Subject: [PATCH] regulator: lp8788-ldo: Let core handle GPIO descriptor
Use the gpiod_get() rather than the devm_* version so that the regulator core can handle the lifecycle of these descriptors.
